    Assessment of Blasting-Induced Ground Vibration in an Open-Pit Mine under Different Rock Properties by Zhi-qiang Yin, Zu-xiang Hu, Ze-di Wei, Guang-ming Zhao, Ma Hai-feng, Zhuo Zhang, Rui-min Feng

    Published 2018-01-01
    “…With increasing joint degree, the attenuation rate of the vibration velocity and energy attenuation of the blasting vibration increase, indicating that the structural parameters of the rock mass (such as the number of joints) have a significant impact on the attenuation law of blasting vibration. Furthermore, a modified equation that can be used for predicting PPV was developed by considering the effect of the number of joints in the rock mass on the blasting vibration. …”
